Speed Control of Switched Reluctance Motor using Sliding Mode Variable Structure Control

介绍了1种采用滑模变结构控制策略的开关磁阻电机速度控制系统。该系统通过将转矩控制内环和速度控制外环相结合,在滑模控制器中加入了加速度估计,改善了系统性能。通过对电机的速度特性进行仿真,证明其滑模控制方法简单,鲁棒性强,且加速度估计器的运用减小了滑模抖振。

A sliding mode variable structure control for switched reluctance motor （SRM） speed control system is presented. System performance is improved by combining the torque control inner loop and the speed control outer loop, and the acceleration estimation is also added to the sliding mode controller. The speed performance of switched reluctance motor is implemented through simulation. The results show that sliding mode control for SRM is very simple and robust, and the application of the acceleration estimation reduces the sliding mode chattering.
